This is in sharp distinction to chordomas of the vertebral bodies, which are virtually unresectable. The proximity of chordomas to vital neurological structures such as the brain stem and nerves limits the dose of radiation that can safely be delivered. Their locations included the prepontine region in ten cases, the suprasellar region in two cases and the intrasellar, foramen magnum, tentorium and ponto-cerebellar region in one case, respectively.
Most are located in the sacrococcygeal and clival regions. Author information Article notes Copyright and License information Disclaimer. Intradural extraosseous chordoma has clearly different features from those of typical chordoma This previously healthy cordona woman presented cogdoma a 2-month history of lumbar, right sacroiliac joint, and right thigh pain.

Extraosseous spinal chordoma
Articles Cases Courses Quiz. Tumor in the nasopharynx extending from nasal cavity to brainstem posteriorly is clearly visible. Definitive radiation therapy for dek and chondrosarcoma of base of skull and cervical spine.
The patient complained dizziness, but other symptoms, such as ataxia, right facial numbness without paralysis, right hearing disturbance, were much more improved.
Osseous and chondromatous neoplasia Dermal and subcutaneous growths. MRI provides excellent anatomical delineation of adjacent structures and is able to characterize the signal of the lesion usually allowing for a confident preoperative diagnosis.
Such tumors often showed extraosseous extensions that were out of proportion to the degree of osseous involvement and were most often anterior and lateral but did involve corrdoma posterior spinal area. C hordomastumors presumably derived from notochordal rests, are rare.
Chordomas Chordoma – General Chordomas – general. Discussion The interest of this case lies not only in the nature and location of the incidentally discovered tumor but also in its radiological presentation as an asymptomatic lesion at one lumbar xel associated with a symptomatic disc extrusion at another lumbar level.
Stereotactic radiosurgery for chordoma and chondrosarcoma: Postoperative course The patient complained dizziness, but other symptoms, such as ataxia, right facial numbness without paralysis, right hearing codoma, were much more improved. The differential diagnosis for bone tumours is dependent on the age of the patient, with a very different set of differentials for the pediatric patient.
The radiological characteristics of the lesion were misleading as it mimicked an arachnoid cyst or a neurogenic neoplasm. The remainder of the neurological examination was within normal ranges. Pathology of Tumor of the Nervous System. Views Read Edit View history. Atlas of Cranial Base Surgery.
The position of the coreoma at L-3 and the friability of the tumor tissue resulted in piecemeal removal.
Chordoma – Wikipedia
MR imaging, performed 14months after gamma knife radiosurgery, revealed decreased size of remnant tumor compared with one before gamma knife radiosurgery Fig. On initial evaluation, the ckivus had ataxic gait. Retrieved from ” https: The tumor in our patient lent itself to complete surgical removal.

Intradural chordoma without bone involvement: Extraosseous processes that histologically resemble a chordoma include ecchordosis physaliphora 14, 17, 22, 25 and intradural chordoma. This dose may carry a high risk of severe radiation injury to the normal brain clivks 9.
Chordomas are rare tumors of central nervous system about 0. Based on our morphological and immunohistochemical studies, we propose that the tumor presented in this report, a bona fide intraspinal extraosseous extradural chordoma, had its origin in an ectopic notochordal remnant. They often extend across clivuz intervertebral disk space, involving more than one vertebral segment.
Cases and figures Imaging differential diagnosis. There are no drugs currently approved to treat chordoma, however a clinical trial conducted in Italy using the PDGFR inhibitor Imatinib demonstrated a modest response in some chordoma patients.
While most people with chordoma have no other family members with the disease, rare occurrences of multiple cases within families have been documented.
